These socks use combed cotton yarn, which is a very soft version of regular cotton. Combed cotton doesn't have any impurities or short protruding threads, is stronger than regular cotton, and is made by treating the cotton fibers before they are spun into yarn.
First pair of CHUP socks. Nice fit, very comfortable!! I'm a size 8US and the M fits me well.
Incredible socks. Super comfy, fresh look. Instant drip.
